본 연구는 적포도주의 첨가가 돈육 patty의 냉장 중 품질에 미치는 영향을 검토하기 위하여 적포도주를 첨가하지 않은 돈육 patty(대조구), 적포도주를 1% 첨가한 돈육 patty(RW-1), 적포도주를 3% 첨가한 돈육 patty(RW-3) 및 적포도주를 5% 첨가한 돈육 patty(RW-5)등 네 종류의 돈육 patty를 제조하고, 냉장 중 보수력, 표면색깔, pH, TBARS값, VBN 함량 및 총균수를 측정하였다. 보수력은 냉장 중 현저하게 증가하였으나, 적포도주의 첨가에 의한 영향은 없었다(p<0.05). 돈육 patty의 $L^*,\;a^*$ 및 $b^*$값은 적포도주 첨가에 의하여 낮아졌으며, 냉장 중 감소하는 경향이었다(p<0.05). pH는 냉장 기간이 경과하면서 증가하는 경향이었으며, 적포도주를 3 및 5% 첨가한 돈육 patty가 대조구 및 적포도주 1% 첨가구보다 낮게 나타났다(p<0.05). TBARS값은 냉장 기간이 경과하면서 현저하게 증가하였으며, 적포도주 첨가량이 증가함에 따라 TBARS값은 감소하는 경향이었다(p<0.05). 돈육 patty의 VBN함량은 냉장기간의 경과와 함께 유의하게 증가하였으며, 총균수도 냉장기간에 의하여 증가하였다. 그러나 적포도주의 첨가가 VBN 함량과 총균수의 증가를 억제하는 경향이었다. This study was carried out to investigate the effect of addition of red wine on the water holding capacity, surface color, pH, TBARS value, VBN content and total bacterial counts of pork patties during cold storage. Pork patties were prepared by four type such as pork patty without red wine (control), pork paoy containing red wine 1% (RW-1), pork patty containing red wine 3% (RW-3) and pork patty containing red wine 5% (RW-5). The water holding capacity was increased significantly during cold storage, but was not influenced by addition of red wine (p<0.05). The $L^*$ (lightness), $a^*$ (redness) and $b^*$ (yellowness) value was low by addition of red wine, was decreased during cold storage (p<0.05). The pH of pork patties were tend to increased with increase in cold storage period, the pH of RW-3 and RW-5 were significantly lower compared to control and RW-1 (p<0.05). The TBARS value of pork patties were tend to increased with increase in cold storage period, by increasing the amount of addition of red wine, the TBARS value were tend to decreased (p<0.05). The VBN content and total bacterial counts of pork patties were tend to increased with increase in cold storage period, and by increasing the amount of addition of red wine, the VBN content and total bacterial counts were tend to decreased during cold storage.

Four types of pork patty were prepared; pork patty without red wine (control), and with the addition of 1%, 3% and 5% red wine (RWP-1, 3 -and t respectively). The pork patties were stored for 5 months at $-20^{\circ}C$. The water holding capacity was significantly decreased during frozen storage, which was not influenced by the addition of red wine (p<0.05). The thawing loss and cooking loss were significantly increased during frozen storage, which also was not influenced by the addition of red wine (p<0.05). There were no significant differences in the diameter and thickness changes during frozen storage, which was not influenced by the addition of red wine (p<0.05). There were no significant differences in the $L^*\;and\;b^*$ values, but the a value was significantly decreased during frozen storage. The $L^*,\;a^*\;and\;b^*$ values of the pork patties containing red wine were lower than those of the control patties (p<0.05). There were no significant differences in the pH and VBN content during the frozen storage period or on the addition of red wine to the patties. The TBARS value of the pork patties tended to increased with increasing in frozen storage period, but were decreased with increasing amount of red wine addition (p<0.05).

The samples consisted of the pork patty without red wine(control), and 1, 3 and 5% red wine(RWP-1, 3 and 5, respectively). There were no significantly differences in the moisture$(58.1\sim58.7%)$, crude protein$(15.9\sim16.3%)$ crude fat$(23.2\sim23.7%)$, and crude ash$(2.7\sim2.9%)$ contents, and the Hunter's $a^*-value(0.2\sim0.6)$, cooking loss$(16.5\sim19.2%)$, VBN$(11.9\sim15.6mg%)$, total bacterial count($(11.9\sim15.6mg%)$ Log cfu/mL), hardness$(3,193\sim3,336\;dyne/cm^2)$, springiness$(75.8\sim79.7%)$, cohesiveness$(47.8\sim52.1%)$, gumminess$(489\sim509kg)$, chewiness$(183\sim209g)$ and strength $(1,144\sim1,199g)$ between the pork patties. Of the pork patties the $L^*$ value of the control and the b value of RWP-5 were the lowest(p<0.05). The pH and TBARS value of RWP-5 were the lowest of all the pork patties. The flavor of RWP-5 was superior to that of the other pork patties, and the taste, texture, juiciness and palatability of RWP-3 and RWP-5 were superior to those of the control and RWP-1. In conclusion, the addition of 5% red wine was most suitable for enhancing the physicochemical properties and sensory score of pork patties.

This study investigated the extractability, solubility, Mg$^{2+}$-, Ca$^{2+}$- and EDTA-ATPase activity of actomyosin prepared from leg and breast muscle of dog meat. The actomyosin extractability of breast muscle(2,100.6 mg/l00 g) was higher than that of leg muscle(500.8 mg/l00 g). The Mg$^{2+}$-ATPase activity of actomyosin had a high ionic strength of 0.02$\sim$0.05 M KCI and did not differ between leg and breast muscle. The Ca$^{2+}$-ATPase activity of actomyosin had a high ionic strength of 0.02$\sim$0.10 M KCI and leg muscle had a higher level of Ca$^{2+}$-ATPase activity than breast muscle did. The EDTA-ATPase activity was lower in low ionic strength and showed higher in high ionic strength, and increased sharply with increasing ionic strength up to 0.3 M KCI. The solubility of actomyosin did not differ between leg and breast muscle, and the solubility started and ended at KCI concentrations of 0.35 M and 0.4 M, respectively.

This study was carried out to investigate the effect of ultrasonic wave scanning on the quality of fried chicken breast. The ultrasonic wave scanning time was 0(US-0), 3(US-3), 7(US-7) and 10(US-10) minutes, no respective comparison here. The moisture of raw breast was higher than that of flied chicken, while the crude protein, fat and ash of fried chicken were higher than those of raw breast(p<0.05). The moisture content was influenced by the ultrasonic waves scanning, but the crude protein, fat and ash were not. The $L^*$(lightness) and $b^*$(yellowness) values of fried chicken were higher than those of raw breast but the $a^*$(redness) value of raw breast was higher than that of fried chicken. The $L^*$ value was lowest in US-0, while the $a^*$ value was not significantly different and the $b^*$ value was lowest in US-7 among the fried chicken samples(p<0.05). The fried chicken was not influenced by the ultrasonic wave scanning, indicating that the longer scanning time increased the water holding capacity. The pH ranged from 6.54 to 6.93, and the calorie of fried was higher than that of raw breast, but was not influenced by the ultrasonic wave scanning time. The VBN content ranged from 8.73 to 12.3 mg%. The TBARS value of raw breast was lower than that of flied chicken and was not influenced by the ultrasonic wave scanning time. Total amino acid was highest in raw breast and lowest in US-3(p<0.05). The taste, texture and juiciness were superior with increasing scanning time, but flavor and Palatability were not significantly different among the fried chicken samples(p<0.05).
